Compression bandage with optimized surface

Abstract

A compression bandage formed by a knit obtained by warp stitch technology, based on synthetic yarns which is made up of two textile surfaces whose textile structure is identical or different connected to each other by spacer yarns. Each textile surface has elastic yarns and the spacer yarn being a monofilament. The knit has a longitudinal elongation measured according to standard EN 14704-1 of between 30 and 160%. The textile surface which comes into contact with the skin has synthetic multifilament yarns, the filaments of which have a count of between 1.2 and 5 dtex and the number of filaments is between 15 and 150, and a dynamic coefficient of friction measured according to standard EN ISO 8295 greater than or equal to 0.25 and less than or equal to 1.2.

         2 . Compression bandage according to  claim 1 , wherein the spacer yarn is a monofilament having a titre comprised between 20 and 80 dtex. 
     
     
         3 . Compression bandage according to  claim 1 , wherein said knit has a side which has a textile structure among the following list:
 charmeuse;   single cord lap fabric with open or closed loops;   atlas under one or more rows;   pillar stitch with open or closed loops, or alternating closed and open loops, said side being opposite the side designed to be brought into contact with the skin, which has a textile structure which is a net having an openwork textile structure.   
     
     
         4 . Compression bandage according to  claim 1 , wherein the knit has a thickness comprised between 1 and 2 mm. 
     
     
         5 . Compression bandage according to  claim 1 , wherein the knit has a space between the sides comprised between 0.4 and 1.5 mm. 
     
     
         6 . Compression bandage according to  claim 1 , wherein the knit has a grammage comprised between 160 and 370 g/m 2 . 
     
     
         7 . Compression bandage according to  claim 6 , wherein the knit has a grammage comprised between 160 and 300 g/m 2 . 
     
     
         8 . Compression bandage according to  claim 1 , wherein the knit has a longitudinal elongation such as defined in standard EN 14704-1 comprised between 70 and 100%. 
     
     
         9 . Compression bandage according to  claim 1 , wherein the side coming into contact with the skin has a quantity of multifilament thermoplastic yarns of around 15 to 40% by mass percentage relative to the total weight of the 3D knit and typically around 20 to 25%. 
     
     
         10 . Compression bandage according to  claim 1 , wherein the elastic yarn has a titre comprised between 40 and 80 dtex. 
     
     
         11 . Compression bandage according to  claim 1 , wherein the textile surfaces comprise thermoplastic yarns haying titres from 40 to 90 dtex. 
     
     
         12 . Compression bandage according to  claim 1 , wherein the side coming into contact with the skin has a dynamic coefficient of friction measured according to standard EN ISO 8295 greater than or equal to 0.25 and less than or equal to 0.5. 
     
     
         13 . Compression bandage according to  claim 1 , wherein the textile surface coming into contact with the skin is a physically-treated surface. 
     
     
         14 . Compression bandage according to  claim 13 , wherein the textile surface coming into contact with the skin is a sueded surface. 
     
     
         15 . A kit comprising one or more compression bandages according to  claim 1  and one or more wound dressings designed to be positioned on a wound prior to the compression bandage.
